# Mark up screenshots right on the page

*Product update · October 27, 2026*

Until now, Select Area worked in two steps. You dragged a region, and then you marked it up in a separate editor tab. In Screencap 1.3, the editor opens on the page itself. You select, draw, and copy without leaving the tab.

*Exported from the in-page editor: numbered steps, a spotlight, an arrow and a text label.*

## How it works

1. Press **Alt+Shift+A**, or click the toolbar icon and choose **Select Area**. Screencap freezes the visible tab, so menus and animations stay where they are.
2. Drag over the part you want. A label shows the size in pixels. Drag the handles to resize, or press the arrow keys to move the selection 1 px at a time (10 px with Shift).
3. Pick a tool and draw on the selection. Tools and actions appear next to it.
4. Press **Enter** to copy the result to the clipboard and close the editor. Press **Ctrl+S** to save it as a PNG.

Press **Esc** at any time to cancel. While the editor is open, your keystrokes and scrolling don't reach the page underneath.

## One key per tool

| Key | Tool |
| --- | --- |
| M | Adjust the selection |
| V | Select, move and resize annotations |
| R | Rectangle |
| A | Arrow |
| L | Line |
| P | Pen |
| H | Highlighter (hold Shift to keep it straight) |
| T | Text |
| N | Numbered steps: each click adds the next number |
| S | Spotlight: dims everything outside the boxes you draw |
| X | Pixelate |
| B | Blur |

Six colors and three stroke widths sit in the same toolbar. **Ctrl+Z** undoes and **Ctrl+Y** redoes. **Delete** removes the selected annotation. If you delete a numbered step, the other steps renumber.

## Actions next to the selection

- **Copy** (Enter) and **Save** (Ctrl+S).
- **Upload** puts the image on Screencap Cloud and gives you a share link. This needs Google sign-in.
- **Auto-redact** finds emails, card numbers, API keys and other sensitive text in the selection and covers them. It runs on your device. See [Hide secrets before you share](https://screencap.app/blog/auto-redaction/).
- **Extract text** reads the selection with the local OCR engine (English).
- **Edit in Screencap** opens the full editor with your annotations. Use it to crop, add a background or a browser or device frame, or export as JPEG, WebP or PDF.

## When it doesn't open

Chrome doesn't let extensions run on some pages: `chrome://` pages, the Chrome Web Store, and the built-in PDF viewer. On those pages Screencap can't open the editor.

If Alt+Shift+A does nothing, another extension may use the same shortcut. Open `chrome://extensions/shortcuts` and set a different one.
